Pull exercise training device

Abstract

A pull exercise training device has a frame body, a reel including a shaft, a rolling wheel, a driver pulley wheel and at least one mainspring, a band connected to the rolling wheel with an end, a load force device including a first axle through a flywheel and a driven pulley wheel, a one way clutch disposed between the first axle and the flywheel, a belt winding around the driver pulley wheel and the driven pulley wheel, a generator set, and a control circuit having a controller electrically connected to a resistor, an armature, and an interface for operation.

What is claimed is: 
     
       1. A pull exercise training device, comprising:
 a frame body; 
 a reel including a shaft engaging the frame body with a rolling wheel arranged therethrough, a driver pulley wheel, and at least one mainspring; 
 a band connecting to the rolling wheel with an end thereof and to a pull bar with the other end thereof; 
 a load force device including a first axle engaging the frame body with a flywheel and a driven pulley wheel arranged therethrough; 
 a one way clutch disposed between the first axle and the flywheel; 
 a belt winding around the driver pulley wheel and the driven pulley wheel; 
 a generator set including a plurality of magnets disposed along an inner surface of a hub of the flywheel and an armature engaging a holder to be disposed in correspondence to the magnets; and 
 a control circuit including a controller and a resistor disposed in the frame body, said controller electrically connected to the armature for stable power supply, to the resistor for control of electric currents, and to an interface for setting and adjusting by a user. 
 
     
     
       2. The pull exercise training device as claimed in  claim 1 , wherein the flywheel includes a plurality of blades. 
     
     
       3. The pull exercise training device as claimed in  claim 2 , wherein a second axle is further engaging through a guiding wheel then fixed to the frame body for the band to wind around. 
     
     
       4. The pull exercise training device as claimed in  claim 2 , wherein the shaft engages the frame body, fixed by a pair of first bearings and a pair of first bearing caps; the second axle engages through the guiding wheel and is fixed by a pair of second bearings; the first axle is fixed to the holder by a pair of third bearings and a second bearing cap. 
     
     
       5. The pull exercise training device as claimed in  claim 2 , wherein the frame body further includes a protective cover for the mainspring and a bar latch for the pull bar to be positioned. 
     
     
       6. The pull exercise training device as claimed in  claim 2 , wherein a tensioner is arranged for the belt to wind around. 
     
     
       7. The pull exercise training device as claimed in  claim 6 , wherein the tensioner further engages a positioning piece and a positioning element by a fourth bearing to be fixed to the frame body.
